Abstract

An adhesive mat for determining a distribution of agricultural spreading material by imaging, includes: a collecting region which is bordered on one side by an edge region, where the edge region includes a passage opening and/or a handle.

First claim

The invention claimed is:

1. Adhesive mat for determining a distribution of agricultural spreading material by imaging, the adhesive mat comprising:
a collecting region which is at least in part confined at least on one side by an edge region,
wherein the collecting region comprises a plurality of knob-like elevations which are arranged in a grid on said collecting region,
wherein the plurality of knob-like elevations forms a plurality of collecting spaces,
wherein the plurality of collecting spaces is configured to retain grains of the spreading material at the points where they impinge on the adhesive mat,
wherein the collecting region further comprises at least one marking, and
wherein the at least one marking is formed by recesses in the grid of the plurality of knob-like elevations.

2. The adhesive mat according to claim 1 , where said at least one marking is formed by recesses in said grid of said plurality of knob-like elevations.

3. The adhesive mat according to claim 1 , where said collecting region is formed to be rectangular and said at least one marking is arranged in each corner of said collecting region.

4. The adhesive mat according to claim 1 , where said passage opening has an extension along one axis located in the plane of said adhesive mat between 90 mm and 350 mm, and said passage opening has an extension along a second axis located in the plane of said adhesive mat, which is perpendicular to the first plane, between 35 mm and 100 mm.

5. The adhesive mat according to claim 1 , wherein the adhesive mat is configured to determine a distribution of agricultural spreading material by imaging.

6. The adhesive mat according to claim 5 , wherein:
said adhesive mat is arranged at a location on a field or test surface; and
granular spreading material from a spreader vehicle passing said adhesive mat is spread over said adhesive mat,
wherein a distribution of said spreading material on said adhesive mat is determined by an imaging method.

7. The adhesive mat according to claim 6 , where the passage opening in said edge region of said adhesive mat is configured as a handle for carrying said adhesive mat.

8. The adhesive mat according to claim 1 , where said at least one marking is used to determine the correct positioning of a camera.
